Spawning A Physics Gun

How on Earth do I spawn just the world model of the physics gun? I can’t find it anywhere on the search menu.

The physgun is basically the grav gun with skin 2, No idea how to spawn it with different skin.

You can add it to the spawnlist. If you really cant do it by yourself ill post it in a sec.Yes, you will be able to spawn it on any gmod server that allows you to spawn props.
